The messages also reveal that lawyer with whom Trump Jr. met, Natalia Veselnitskaya, was introduced in the email as a Russian government associate.

In an interview on Tuesday morning, however, Veselnitskaya denied that she had ties to the Russian government. She also said Trump Jr. asked whether she had damaging information about Democrats, particularly in relation to campaign financing.

The meeting of note was also was also attended by Trump Jr., Jared Kushner, and former Trump campaign manager Paul Manafort.

Both Trump Jr. and Veselnitskaya said no actual, significant information about Clinton was shared during the meeting, which makes the claim within the published emails about Russian involvement worth scrutinizing.

Still, at the very least, the emails released by Trump Jr. appear to show a willingness by Trump campaign officials to seek information that would damage its opponent, even if there was a possibility the information came as part of a coordinated effort by the Russian government.
